ABSTRACT:
Improved testing fixture apparatus for use in accurately effecting temporary electrical connections with the test point zones of printed circuit boards or the like is provided in which the board to be tested is mounted upon a locator assembly that is shiftably receivable within the fixture and includes a centering and gripping mechanism operative in conjunction with a cooperative part carried by the contact bearing portion of the fixture for automatically positioning the locator assembly and printed circuit board carried by the latter in a predetermined location within the fixture assuring precise alignment of a contact with each of the test point zones of the printed circuit board to be tested. The positioning action of the mechanism and its cooperating part includes both a centering function and a gripping function therebetween, and both of such functions occur automatically in response to relative shifting of the portions of the fixture for respectively supporting the printed circuit board and the contacts toward each other into an operative relationship for effecting electrical connections between the test point zones of the printed circuit board and corresponding contacts of the fixture.
